Nirvana - Something In The Way
Regina Spektor - Field Below
Eric Clapton - Tears In Heaven
The Beatles - She Came In Through The Bathroom Window
Paramore - Crushcrushcrush
Not too bad. I have a tonne of music in my iTunes library that I have yet to listen to, so I was half expecting to not know most of what came up. These don't describe my taste too well though - I prefer more indie/rock/alt stuff.
Edit: I decided to try my iPod instead (which is more narrowed down than my iTunes library) and this is what came up:
The Shins - Turn On Me
Foo Fighters - The Pretender
Kesha - Take It Off
Biffy Clyro - Many Of Horror
Biffy Clyro - When The Faction's Fractional
Much better. Biffy's my favourite band, so I'm not surprised they came up more than once.
